The maps shows the time series of yearly vegetation productivity anomalies under drought impact aggregated by NUTS3 regions. Negative anomalies indicate vegetation productivity conditions which are lower than the long term average normal condition. The time series spans over 2000-2016 and individual years can be explored be choosing the year of interest in the drop-down filter.

Anomalies are expressed in standard deviations compared to the long term average vegetation productivity conditions for each 500m grid cell in the EEA39 region. Negative vegetation productivity anomalies indicate vegetation productivity conditions that are less than the long term normal condition.

The extent of the impacted area is calculated from the sum of those grid cells where the vegetation productivity anomaly was below -1 standard deviation in the given year.

In order to exclude low vegetation anomaly signals in the time series, only those grid cells were considered in this analysis where the Corine Land Cover (CLC) 2000-2018 series indicated no land use change between 2000-2018.
